Yesterday I used Ccleaner to erase my old laptops hard drive, as I plan to sell it on and didn't want to leave any personal data on it. I was planning on reinstalling Windows 7 on the laptop, but every time I turn the laptop on I'm met with a screen saying "BOOTMGR is missing Press Ctrl + Alt + Del to restart" . I can access the BIOS, and have changed the boot order so it boots from the DVD drive first, but it still shows the BOOTMGR is missing screen. Anyone know what I can do to fix this problem?
